Grid computing architecture was defined to be a complete physical layer. Shared data systems have grown in numbers and hence they are susceptible to many security challenges. The authors proposed the encryption algorithm, i.e., N-th degree TRUncated polynomial ring (NTRU) in every grid node to keep the information in security. Sender requests key code from receiver node. By using this key code, sender encrypt message using N-th degree TRUncated polynomial ring (NTRU) schema to produce cipher text and sent out. The receiver once received proceeds to decrypt the cipher text and gets back the original message from the received text. To decrypt the message, same key code is used by receiver.
